Hello there @943023!
As a first step, please make sure the variable change has not created any redirectors, compile your blueprints, and avoid generating a nested structure.
Second of all, could you provide specifics about the variable added to the structure, what was exactly changed? Is the issue affecting a single project, or is the crash affecting fresh, new files? Additionally, please provide the full logs of the crash, instructions for the process can be found here:
Crash reports from the editor are stored on your local machine in your project’s
Saved/Crashesfolder.Alternatively, you can find crash reports on a user’s local machine in
C:\Users[Your Windows Username]\AppData\Local[Project Name]\Saved\Crashes.
